ICW1232A33PGQ1 from ICW, in a SOT-89-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VSS | power_in | Ground pin (地) that serves as the return reference for the regulator, with the absolute maximum ratings for VIN, CE and VOUT referenced to VIN and VSS. |
| 2 | VIN | power_in | Voltage input pin with an operating range of 1.8V to 5.5V and an absolute maximum VIN pin voltage range of -0.3V to 6.5V. |
| 3 | VOUT | power_out | Regulated voltage output pin with a maximum output current of 400mA (VIN=4.3V, VOUT=3.3V) and an absolute maximum output current of 600mA. |
